  Randomizing text type-on rate

  Posted by Navarro Parker on February 20, 2013 at 6:17 pm

  I’m using an expression for writing on text (it also has a cool blinking leading cursor) that I found here:
  https://ae.tutsplus.com/tutorials/motion-graphics/quick-tip-type-on-text-preset-with-blinking-cursor/

  How would I modify it so that the type-on rate isn’t constant — so it replicates the slight uneven typing speed of a human being? I’ve tried using Wiggle on the Speed slider, but that has the unintended effect of the text sometimes going backward.

  L = text.sourceText.length;
It = time - thisLayer.inPoint;
sp = effect("Speed")("Slider")
st = effect("Start After")("Slider")
bl = effect("Cursor Blink")("Slider"); // value 0 off ~ 10 very fast
T = It * sp - st;
F = Math.round(( It * bl) % 1 );
if(F==1 | (T0) ){Fl="|";}else{Fl="";}
substr(0,T) + Fl
